Abstract

A problem is to provide a fine resin particle formed by a simple method and capable of preventing fine resin particles from dropping out from substrates or binders and imparting scratch resistance to films, and a fine resin particle-containing composition. A solution is to provide a fine resin particle obtained by polymerizing one or two or more vinylic monomers and, in an infrared spectrum measured by an ATR method with an infrared spectrophotometer, having an absorbance ratio (B)/(A) in a range of 0.020 to 0.060 between the maximum peak height (maximum absorbance) (A) in a wavenumber range from 1700 cmto 1800 cmand the maximum peak height (maximum absorbance) (B) in a wavenumber range from 1600 cmto 1700 cm.
